The Bosch Rexroth AA4VG56EP4D1/32R-NSC52F076BP (R902249783) is a high-performance axial piston variable pump designed for hydrostatic transmissions in closed circuits. This particular model is notable for its integrated boost pump, which ensures the supply of boost and pilot oil. The flow direction within this unit changes smoothly, thanks to the precise movement of the swashplate through the neutral position, enhancing the operational efficiency and control. Engineered with high-pressure relief valves that include an integrated boost function, this pump provides reliable performance under demanding conditions. It comes standard with an adjustable pressure cutoff, allowing users to set and maintain optimal operating pressures according to specific application requirements. The inclusion of a boost pressure relief valve further contributes to its safety and longevity. The AA4VG56EP4D1/32R-NSC52F076BP offers versatility through its through-drive capability, which permits the mounting of additional pumps up to the same nominal size directly onto it, facilitating complex hydraulic systems without requiring extra space. This feature streamlines system design and can lead to cost savings in terms of materials and installation time. Constructed with a robust swashplate design, this Bosch Rexroth pump is built for durability and consistent performance. Its wide range of controls enhances adaptability, making it suitable for various applications that require precise hydraulic fluid management. Whether used in mobile or industrial applications, this axial piston variable pump stands out for its reliability, customization options, and efficient operation.
